秸秆还田与减量施肥对双季稻产量及土壤酶活性的影响
Effect of Straw Application and Fertilizer Application Reduction on the Double Cropping Rice Output and Soil Enzyme Activity
摘要
Abstract
The thesis studied on the output of double cropping rice and the effect of soil enzyme activity with straw returning to the field based on optimizing fertilization by field experiment. The results revealed that both optimizing fertilization without any reduction or reduction to a certain ammount of N,P,K,could reduce the output of early rice and double cropping rice, but the effect, reducing or increasing, was not ob-vious on late rice. With straw returning, soil enzyme activity,all markedly damaged urease activity. Soil enzyme activity improved soil sac-charase activity when reducing fertilizing amount of K and damaged soil cellulase activity when reducing fertilizing amount of N.关键词
